The paper presents the thermodynamic analysis of adenine adsorption on a mercury electrode in an acetate buffer at pH 3 and pH 4. Adsorption energy and constants were determined using the Frumkin isotherm and the virial isotherm. Stronger adsorption in the buffer at pH 3 was observed in comparison to the buffer at pH 4. Using cyclic voltammetry and Faraday impedance measurement, an inhibitory effect of adenine on the kinetics of Zn (II) ion electro-reduction was observed.
本文介绍了在pH值为3和pH值为4的醋酸盐缓冲液中腺嘌呤在汞电极上吸附的热力学分析。使用弗鲁姆金等温线和维里等温线确定了吸附能和常数。与pH值为4的缓冲液相比，观察到在pH值为3的缓冲液中吸附更强。通过循环伏安法和法拉第阻抗测量，观察到腺嘌呤对Zn（II）离子电还原动力学的抑制作用。
